Περίληψη | Major and trace chemical elements from eleven Lower Pleistocene bentonite
deposits from Eastern Milos Island, Aegean, Greece, were used for geochemical fingerprinting of the
bentonites, by means of scatter binary and ternary plots and canonical discriminant analysis. The
trace elements were selected according to their immobility during bentonite formation and
subsequent hydrothermal alteration. The bentonites can be separated into at least four geographically
distinct groups, each consisting of materials with similar geochemical affinities. The deposits of each
group were derived from protoliths erupted from different volcanic centres, suggesting the existence
of at least two distinct volcanic provinces, having rhyolitic and andesitic affinities respectively.
Several deposits consist of more than one bentonite horizon, indicating that in some volcanic centres
the character of volcanism changed with time. Geochemical fingerprinting, supplemented with
geological, mineralogical, and textural evidence, may be useful for correlation and exploration of
bentonites, in terrains with complex geological histories. | en |
